6.Rear Stacker (face up)
Capacity 100 sheets
When the rear paper stacker is folded down, paper exits
the printer through the rear of the printer and is stacked
face up.
This is used for labels, heavy print media, envelopes and
custom paper sizes.
When used with the Multi-Purpose Tray, the paper path
through the printer is essentially straight. This avoids
bending the print media around curves in the paper path
and makes paper feeding more reliable.

Paper (Print Media)
General Information _____________________
CAUTION!
Print media must be able to withstand 446°F (230°C)
for 0.2 second.
You need to know three characteristics about any paper (print
media) you want to use with your printer:
• Type
• Weight
• Size
The type, weight, and size of the paper (print media)
determine:
• which paper feed tray can be used
Choices are multipurpose tray (MP Tray/manual feed)
or Trays 1 - 2
• which paper exit path can be used
Choices are face-down or face-up (straight-through)
• whether you can use double sided (duplex) printing
For type, see
• Paper: US Bond (Metric): see page 16
• Paper: Index: see page 18
• Letterhead: see page 20
• Envelopes: see page 24
• Transparencies: see page 29
• Labels: see page 26
For weight, refer to the correct paper type. Each paper type
has a table (matrix) of paper size, paper weight, paper feed,
paper exit, simplex/duplex correlations.
For general information on paper sizes, see “Paper Size, Feed,
and Exit” on page 35.

If you are printing on a thick media such as card stock,
be sure to select one of the thicker settings to get
proper fusion of the toner to the page and to prevent
possible damage to the printer.
Select the thickness/type of media on which you are
printing a particular job, to produce optimum print
results. This setting overrides the setting in the printer

Recommendations
•Check www.okiprintingsolutions.com for the latest
information on recommended papers for your printer.
•Paper should be stored flat, away from moisture, direct
sunlight and heat sources.
•The use of heavily laid or textured paper will
seriously affect the life of the image drum and give
poor print quality. Print quality can be improved by
changing the media setting to ‘Ultra Heavy.’ However,
this will reduce the output speed and prevent the use of
the duplex option.
•Avoid:
– Damp, damaged or curled paper.
– Very smooth, shiny or glossy paper.
– Heavily embossed letterhead paper, very rough paper
or paper that has a large grain difference between the
two sides.
– Paper with perforations, cut-outs or ragged edges.
– Carbon paper, recycled paper, NCR paper,
photosensitive paper, pressure sensitive paper or
thermal transfer paper.
